Frequently Asked Questions

4 Q&As

Do the generated QR codes ever expire?

No. These are static QR codes that encode your data directly into the matrix. They will function permanently without fees or expiration dates.

Are there scan limits or hidden paywalls?

Never. You get unlimited scans forever with no subscription or account required.

What is Error Correction Level (ECC)?

ECC allows QR codes to remain scan-readable even if up to 30% of the code is smudged, damaged, or covered by a custom logo.

Can I print these QR codes on large posters and billboards?

Yes! Download in vector SVG format for infinite scalability without any pixelation or blur.
